ALBERT RONTKE, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO THE SINGER MANU-FACTURING COMPANY, A CORPORATION OF NEW JERSEY.

FABRIC-GUIDING ATTACHMENT: FOR. SEWING-MACHINES.

To all whom it may concern:

Be it known that I, ALBERT RoN'rKE, a citizen of the United States,residing at Bridgeport, in the county of F airfield and State ofConnecticut, have invented certain new and useful Improvements inFabric- Guiding Attachments for Sewing-Machines, of which the followingis --a specification, reference being had therein to the accompanyingdrawings.

This invention relates to improvements in fabric-guiding attachments forsewing machines, and has for its object to provide improved means forpositioning and securing the attachment with respect to the line ofneedle actuation.

In the earlier constructions of fabric-guiding attachments provided withmultiple guiding elements, as is theimproved device, the effectiveadjustment of the separate guides is confined to a line substantiallytransverse to the line of scam formation, while in the present instancethe guiding elements are capable of adjustment in transverse directions,and at any point within the field of such adjustment.

In the accompanying drawings illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure 1 is a planview of a portion of the bed-plate of a sewing machine fitted with theimproved fabric-guiding attachment, Figs. 2 and 3 are plan views of theattachment shown in Fig. 1, and Fig. 4 is a central 9 cross section onthe line AB, Fig. 1.

Referring to the figures, 1 represents the bed-plate of a sewingmachine, 2 the needle or throat plate and 3 the front slide plate ofusual construction.

l represents the fabric guide frame provided with guiding members a, b,c, d, whose guiding surfaces are of different lengths and a centralcircular opening 5 into which latter is rotatably secured a frame cap orsecuring member 8 provided with a slot 9 extending in oppositedirections across the axis of said frame cap, the latter being securedin said frame by forcing the flanges 6 and 7 formed integral with saidcap, in sliding relationship with the inclined wall 11 of said frame, ascrew 10 threaded into the bed-plate 1 acting to secure said guide frameand frame cap in their adjusted positions.

Referring to Fig. 1, the guiding member a is shown at its limit ofadjustment back Specification of Letters Patent.

Serial No. 683,203.

from the needle in a line transverse to the line of scam formation andintersecting the hue of needle actuation, as when employed forcurvilinear edge stitching, and in position capable of being adjustedfor guiding the fabric at any point within the field represented by thedotted lines 6, f, g, 7b; but when the adjustment of the member aislimited to a line transverse to the line of seam formation andintersecting the line of needle actuation, said member can be adjustedback from the needle to the limit of movement permitted by the slot 9,and these conditions of adjustment are true when the member a isadjusted forward or toward the line of needle actuation the distanceindicated by the dotted line 7". i

In Fig. 2 the member a is shown at its limit of adjustment toward and atthe rear of the needle, as when employed in connec tion with a bindingattachment for guiding the bound edge of the fabric.

In Fig. 3 the member a; is shown at its limit of adjustmentto-ward andin front of the needle, as whenused for edge stitching mens collars andcuffs.

From the foregoing it is to be understood that any one of the guidingmembers a, 7), 0, cl, is capable of adjustment at right angles to andparallel with the seam the distance indicated by the lines 6, h and f,g, or at any point within the field represented by such dotted lines,such range of. adjustment being made possible by loosely mounting theframe 4 on the cap 8, in connection with the slot 9 extending across theaxis of said cap.

Claims 1. An edge-guiding device for sewing inachines comprising aguide-frame provided with an edge-guide and a circularly arrangedinclined wall, a cap provided with integrally formed flanges mounted. onsaid frame, said cap being held in effective relationship with saidframe by said flanges which are in sliding relationship with saidinclined wall and provided with a slot extending across its axis, andmeans for securing said frame and cap in their desired relationship.

2. An edge-guiding device for sewing machines comprising a guide-frameprovided with multiple edge-guides whose guiding surfaces are ofdifferent lengths and a circularly arranged inclined wall, a capprovided with integrally formed flanges mounted on said frame, said capbeing held in ef- In testimony whereof, I have signed my fectlverelatlonshlp with sald frame by sultname to this specification, 1n thepresence of able flanges havlng slldlng relationshlp with twosubscribing wltnesses.

said inclined Wall and provided with a slot ALBERT RONTKE. extendingacross its axis, and means for se- Vitnesses:

curing said frame and cap in their desired ABBIE M. DONIHEE,
